CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application Ser. No. 60/613,214 entitled “Passenger keyboard tray & display apparatus,” filed Sep. 28, 2004. The contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

This invention relates generally to keyboard and display apparatus, and systems that facilitate the use of such apparatus, and more particularly, to an arrangement of keyboard and display apparatus attached to, or integrated on or within, the passenger seats of a passenger vehicle or vessel such as an aircraft, and systems and methods for delivering promotional software, services, and content to the users of such keyboard and display apparatus.

BACKGROUND OF THE INVENTION

Computer keyboards and displays are typically discreet apparatus placed on a table, or integrated within a laptop. As computer use grows, there is a need for convenient and continuous access to a variety of software applications and services even while a passenger is in transit or on a moving vessel or vehicle traveling to a destination.

Although internet access is becoming available on trains, aircraft, and the like, the available systems require that the user bring their own access devices such as a laptop PC. When keyboards are provided for internet access, they are typically not provided to users in economy class. Furthermore, economy class passengers are often limited in their ability to open laptop devices while seated next to other passengers. Wires associated with a laptop power adapter or an external mouse are also susceptible to being damaged by other passengers entering or exiting from adjacent seats to the user of such devices.

The inconvenience of security checks at airports, the possibility of theft, and limits on the weight of carry-on items also deter some passengers from bringing laptop devices during their travels.

There is a need for a foldable table apparatus that will serve a dual role, that of the conventional foldable table that passengers are familiar with on an airplane or train, and that of a foldable table keyboard apparatus and display apparatus to permit passengers to access a variety of entertainment services, software applications, and other services during their transit in a convenient and safe manner.

SUMMARY OF THE INVENTION

One aspect of the present invention is to provide a foldable table apparatus that may be used to conveniently access a variety of software and services on a passenger vehicle or vessel such as an aircraft, a bus, a train, a ferry, and the like. Embedded within the table apparatus is a keyboard apparatus, a display apparatus, or both, and typically, connectors may be provided to permit the user to open, edit, and save data files while in transit.

The foldable table apparatus is typically mounted to an array of seats such as that provided in an aircraft, bus, train, but the foldable table apparatus may also be used within theatres, auditoriums, and the like. The foldable keyboard table apparatus may be used as a conventional foldable food table of the type found in an aircraft or train and, when the keyboard or display apparatus is in a closed position, a food tray can be placed on the table apparatus surface without affecting the function of the apparatus. Thus, the passenger may be served food or drinks on the table apparatus at their convenience.

A further aspect of the present invention pertains to a foldable table apparatus that can be embedded with an easy-to-access and easy-to-store flippable keyboard. Typically the keyboard apparatus functions as a wireless keyboard and is associated with a specific display. The keyboard apparatus is readily removable and replaceable if food or beverages affect its function.

Another aspect of the present invention pertains to a foldable table apparatus that can be embedded with various easy-to-access and easy-to-store computer devices such as a Touchpad, Trackpoint, digital camera or web cam, CD/DVD player, gaming and entertainment software, or game controller, thus, enabling a user or passenger to have wide choices in accessing a network or program or for entertainment.

Another aspect of the present invention pertains to a clamshell type foldable table apparatus having a keyboard cover or keyboard lid that protects the inside of the foldable table apparatus in case of spillage.

Another aspect of the present invention pertains to a two-piece foldable table apparatus that can be embedded with various computer devices, a flippable display enclosure and/or a sliding keyboard. The two-piece foldable table apparatus may be used in constrained areas in combination as a foldable table apparatus with an embedded computer device and a foldable food table.

The present invention provides various easy-to-access and easy-to-store keyboard tables such as a foldable armrest keyboard table, rotating keyboard table, retractable keyboard table, hinged keyboard table, and compartment type foldable keyboard table.

The present invention also provides an accessible keyboard or display apparatus mountable to a wall or a horizontal surface. As contemplated by the invention, a foldable keyboard and display apparatus that can be retracted and opened via a keyboard support arm may be mounted to a wall in public areas or to a rear seat of an aircraft.

The present invention also provides an easy-to-access and easy-to-store flippable display panel enclosure having a flippable display panel with an embedded display screen that can be mounted to a horizontal surface in outdoors or in factories.

The present invention further provides an easy-to-access and easy-to-store computer apparatus inconspicuously integrated within a horizontal surface such as a conference table or podium, which is useful for meetings or presentations. In a similar manner, a flippable keyboard may also be inconspicuously integrated within a keyboard drawer of a computer table preventing any clutter or trip hazards caused by unsightly cable connections.

A further aspect of the present invention is to permit the foldable table apparatus or the keyboard apparatus to be cleaned, sterilized, or sealed for each new passenger to prevent the transmission of disease from one user to another. As such, the keyboard apparatus may be easily removed and replaced with a new or cleaner unit.

A further aspect of the present invention is to provide users of an array of such foldable table apparatus a system and method of obtaining internet access, and access to entertainment during their transit. As passengers are typically seated during transit, the system provides third party software vendors and service providers to provide promotional content and access to software applications that passengers may try and purchase if they choose. The passengers may compose emails that may be delivered in real time or when the passenger vessel reaches its destination.

DETAILED DESCRIPTION OF THE INVENTION

A keyboard apparatus, typically integrated within a foldable keyboard table apparatus, an associated display apparatus, a system for receiving wired or wireless data input from and for sending or transmitting data output to such apparatus, and methods for providing complimentary or subscription based software or services to an array of such apparatus fall within the scope of the present invention. The various mechanical forms of the keyboard and display apparatus also fall within the scope of the present invention. Typically, the present invention is directed towards passengers and transient users.

The apparatus is suitable for applications, such as mounted to a seat in a passenger aircraft, a bus, train, ferry, car or taxi, an auditorium, a theatre, a hallway, and the like where it is desirable to have a keyboard and display apparatus that may be accessed, operated, and stored quickly and conveniently. For example, the foldable keyboard table and display apparatus may be set up in the economy class of an aircraft despite the constrained space. The foldable keyboard table and display apparatus can also be adapted to passenger seats inside cars, trains, marine vessels like ferries and boats, or any moving transportation vehicle or vessel. For example, luxury cars or limousines may have a wireless Internet or network connection to the vehicle when it is moving or stationary and such a vehicle may provide a keyboard tray for the traveler. In the same manner, owners and operators of buses, trucks, boats, ferries or trains may provide a similar service. The foldable keyboard table and display apparatus may also be applied in a theater or lecture hall in a university where it serves a dual purpose in that it can access the Internet for research work or display content in line with a presentation. Access to a network, be it wired or wireless, may be provided free of charge or on pay per use or per time scheme. When there is a cost associated with the network access, the system can be adapted to obtain payment from a smart card, prepaid card, credit card, or be billed to a third party.

In one embodiment, a foldable table apparatus is provided having an integrated easy-to-access and easy-to-store flippable keyboard with an associated display screen preferably attached to the rear of a passenger seat in an aircraft or any moving vehicle or passenger vessel and that may be accessed and stored quickly and conveniently while on board. The flippable keyboard may be embedded with computer devices such as a Touchpad (TM) or Trackpoint (TM) style input devices or electronic devices to enhance its functionality and its wireless capability to the host system.

Accordingly, FIG. 1 is a perspective view of a foldable table apparatus 1 incorporating a flippable keyboard 3 and an associated display screen 15. Flippable keyboard 3 is flippably attached to foldable table apparatus 1 and may be flipped from an open position (shown) to a closed position by means of a flipping motion with a finger inserted at 2nd table depression 5. Reversely, flippable keyboard 3 may be flipped from a closed position to an open position by flipping the back of the keyboard with a finger inserted at 1st table depression 4. Typically, flippable keyboard 3 may be used by a passenger seated immediately behind forward seat 12 to facilitate access to a network such as Internet, a specific website or service, an email application, business and other job related programs, music files, or movie files; get attention or request assistance from flight crew attendant and airline staff; or facilitate control of an optional secondary display screen 16 that is dedicated to a particular function such as displaying in-flight movies or accessing and viewing airline or aircraft specific content and in-flight messages for a specific or for all passengers. When no flippable keyboard 3 is present, such as when flippable keyboard 3 is in a closed position, foldable table apparatus 1 resembles a typical foldable food table of the type attached to the rear of a passenger seat in an aircraft.

Flippable keyboard 3 and its data output, and any cursor-pointing device are associated with display screen 15 that is embedded on display panel 77. Display screen 15 is intended for use with flippable keyboard 3 in a manner similar to how a laptop keyboard is associated with a laptop display screen. The result of any keyboard action, command or prompt is displayed on display screen 15. Items that may be seen on display screen 15 include (but not limited to) program applications, data file contents, digital images, contents of internal and external storage devices, media players, and airline contents of general or specific nature directed to the user. Display screen 15 may have a touch-sensitive screen or a screen that responds to inputs from a stylus pen. Display panel 77 is rotatably attached may be pivoted or rotated essentially along display panel rotation direction arrow 18 relative to its default position on forward seat 12; such movements of display panel 77 may improve contrast of displayed images in display screen 15 enhancing comfort of user, reducing glare, and improving legibility.

Flippable keyboard 3 and its associated display screen 15 may be customized and adapted for one or more languages, age groups, or interests. For example, English speaking passengers may use a standard 104-key keyboard while a teenager may prefer a keyboard adapted to listening to music or watching movies. A child may prefer a keyboard adapted for a specific game, zoo animals, TV program, or other interests suitable to the child's age group. A passenger can even request from the flight crew for a specific language keyboard, for example, Chinese or Hindi language keyboards. These language keyboards differ significantly from the English language keyboard typically used.

Foldable table apparatus 1 may be stored in its upright position by compacting it along support arm 9 and upward relative to securing arm 20 and securing it using table latch 19. A food tray (not shown) may be placed on foldable table apparatus 1. The bottom of any food tray placed on foldable table apparatus 1 is prevented from touching any key of keyboard keys 6 by means of the recessed structure of keyboard keys 6. The top of keyboard keys 6 may be lower than table surface 2 so as not to touch the bottom of any food tray placed on foldable table apparatus 1 and thus, prevent any keystroke action. Tray stop 7 prevents items such as a food tray from sliding off onto the lap of the user or passenger. The construction of foldable table apparatus 1 and its component parts will require some measure of protection from corrosion, liquid spillage, dust, and rough handling. Corporate advertisers can use foldable table apparatus 1 as an advertising medium by putting customized graphics and presentations to promote their products or services to the travelers. For example, flippable keyboard 3, keyboard keys 6, and table surface 2 may contain the advertiser's logo or they may contain printed graphics, symbols, letterings, numberings, or instructions in a variety of colors, typefaces, and languages.

FIG. 2 is an isometric view of three foldable table apparatus 1 of FIG. 1 each mounted to the rear of a passenger seat in an aircraft. Forward seat 10 illustrates the attached foldable table apparatus 1 in an upright stored position. Foldable table apparatus 1 may be secured and released by turning table latch 19. The bottom of table apparatus 1 is prominently visible when it is folded upright as illustrated. Display screen 15 may be turned on to display images even when flippable keyboard 3 is in a closed or open position. An optional secondary display screen 16 is also visible and may be powered independently of the position of foldable table apparatus 1 or flippable keyboard 3 (whether closed or open). Forward seat 11 shows foldable table apparatus 1 in a horizontal position with flippable keyboard 3, integrated on foldable table apparatus 1, in a closed position. In a closed position, the bottom of flippable keyboard 3 is prominently visible and flushed with table surface 2 while keyboard keys 6 are not visible. Forward seat 11 also shows foldable table apparatus 1 resembling a typical foldable food table mounted to the rear of a passenger seat in an aircraft. While in the closed position, foldable table apparatus 1 may be used as a table to hold pocket books, magazines, newspapers, portable electronics, food items, food containers, beverages, and the like. Forward seat 12 illustrates foldable table apparatus 1 in a horizontal position, with flippable keyboard 3 in an open position. In this position, keyboard keys 6 of flippable keyboard 3 are prominently visible. The height of table surface 2 is higher than that of keyboard keys 6 in such a way that a food tray could be placed on top of foldable table apparatus 1 without accidentally pressing any key of keyboard keys 6. Thus, a user may pause and have a meal or snack without the inconvenience of removing the keyboard. Forward seats 10, 11, 12 are seats directly in front of the user in a typical aircraft. They may also refer to a commercial or private train, car, or any moving vehicle as mentioned in alternative examples of the present invention.

FIG. 3 is a top view of foldable table apparatus 1 of FIG.1 showing flippable keyboard 3 in a closed position. In the closed keyboard position as shown in FIG. 3, the visible bottom surface of keyboard 3 and table surface 2 are flushed. Thus, in this position, passengers may see what appears to be a typical foldable table with no visible keyboard. As earlier mentioned, the flip-to-open and flip-to-close actions of flippable keyboard 3 may be effected by a flipping means with the passenger holding the edge of flippable keyboard 3 and sliding it via groove pin 23 along groove 22 located on each side of recessed enclosure 8 of foldable table apparatus 1. Supplying power to flippable keyboard 3 may be done either by batteries internal to flippable keyboard 3 or by an external power supply by means of a metallic groove 22 and groove pin 23 to conduct electricity from an external power supply or a recharger to the electronics within flippable keyboard 3. Electronics data may also be transferred to and from the electronics within flippable keyboard 3 using a wireless connection or by conducting signals along metallic groove 22 and groove pin 23.

FIG. 4 is a top view of foldable table apparatus 1 of FIG. 1 showing flippable keyboard 3 in an open position. When flippable keyboard 3 is in an open position, it may be used to run application programs, to access the Internet or aircraft on-board entertainment system, to view movies, listen to music, view flight information, or request for the attendant's assistance. Visible on the open flippable keyboard 3 are keyboard keys 6, one or more LED status indicator lights 24, power supply button 25, USB connection jack 26, and flash memory card reader slot 27. Flippable keyboard 3 is shown flippably attached to foldable table apparatus 1 via groove pin 23.

FIG. 5 is a front view of foldable table apparatus 1 of FIG. 4. Shown in hidden outline is the relative position of groove pin 23 that is attached to flippable keyboard 3 and slidably attached to groove 22. Also shown in hidden outline is recessed enclosure 8 that serves as a housing cavity for flippable keyboard 3. The height of keyboard keys 6 is lower than table surface 2 permitting a food tray to be placed on top of foldable table apparatus 1 without touching any key of keyboard keys 6, thus, foldable table apparatus 1 may also be used as a foldable table.

FIG. 6 is a cross-sectional view of foldable table apparatus 1 taken along lines 6-6 of FIG. 4. With reference to FIG. 6, groove 22, located on both sides of foldable table apparatus 1, secures groove pin 23. The contour of groove 22 follows the shape groove pin 23 to contain the movement of the latter with minimal friction. Keyboard printed circuit board 30, located at front left portion of flippable keyboard 3, contains the electronics necessary for the proper functioning of flippable keyboard 3 and its associated communications and data storage circuitry.

FIGS. 7 . . . 10 illustrate progressions relative to flipping, rotating, and then sliding flippable keyboard 3 of foldable table apparatus 1 from the upright table position to the open horizontal position. The progressions illustrate the ease and almost effortless means in opening flippable keyboard 3 from within foldable table apparatus 1.

Referring now to FIG. 7. FIG. 7 is a schematic side view progression of flippable keyboard 3 of foldable table apparatus 1 as it is rotated from the upright table position to its horizontal table position. As can be seen in FIG. 7, flippable keyboard 3 is rotated from its upright table position 32 as shown in phantom line representation to its horizontal table position 33 essentially along table rotation direction arrow 31. While in the horizontal table position 33, flippable keyboard 3 remains secured in recessed enclosure 8 and stationary relative to foldable table apparatus 1. In this position, the bottom of flippable keyboard 3 may be used as a foldable table of the type mounted to the rear of a passenger seat in an aircraft.

FIG. 8 is a schematic side view progression of flippable keyboard 3 as it is rotated from its 1st keyboard position through a 2nd keyboard position then to a 3rd keyboard position. Flippable keyboard 3 is shown rotated about groove pin 23 while within recessed enclosure 8 from the phantom line representation of 1st keyboard position 50 (closed position), through an essentially diagonal phantom line representation of 2nd keyboard position 51, as indicated by table rotation direction arrow 37, then to an essentially vertical phantom line representation of 3rd keyboard position 52, as indicated by table rotation direction arrow 38. Keyboard bottom surface 36 and keyboard top surface 35 of flippable keyboard 3 are also shown in an essentially vertical orientation. Keyboard top surface 35 contains the embedded keyboard keys 6.

FIG. 9 is a schematic side view linear progression of flippable keyboard 3 as it is moved from one end to the opposite end of recessed enclosure 8. Flippable keyboard 3 is rotated further towards the user from its vertical 3rd keyboard position 52 as shown in FIG. 8, to phantom line representation of 4th keyboard position 53, thereto slid along and rotated about groove 22 to phantom line representation of 5th keyboard position 54 along table rotation direction arrow 40, and continues to progress along groove 22 along table rotation direction arrow 41 to a 6th keyboard position 55. In the 6th keyboard position 55, flippable keyboard 3 is firmly attached to foldable table apparatus 1 by groove pins 23 positioned on respective right and left sides of flippable keyboard 3. Each groove pin 23 is slidably received and secured by its associated groove 22 along each side of recessed enclosure 8 of foldable table apparatus 1.

FIG. 10 is a schematic side view progression of flippable keyboard 3 as it is rotated to its open position. With reference to FIG. 10, flippable keyboard 3 is rotated downwards via groove pin 23 from its 6th keyboard position 55 as shown in phantom line representation to a horizontal 7th keyboard position 56 essentially along table rotation direction arrow 45. It should be noted that groove pin 23 has moved from one end of groove 22 to the opposite end of groove 22 as flippable keyboard 3 is moved from a closed position (1st keyboard position 50) to an open keyboard position (7th keyboard position 56). The mechanical movements of foldable table apparatus 1 and flippable keyboard 3, as illustrated in FIGS. 7-10, may be effected either by a manual effort of a passenger or attendant typically using the arms, hands or fingers, or by electric motors incorporated within or about foldable table apparatus 1, which may effect similar mechanical movements at a press of a button or by remote control. A review of FIGS. 8-10 shows that keyboard top surface 35 of flippable keyboard 3 is progressively rotated and moved from the closed 1st keyboard position 50, where the keyboard top surface 35 is not visible and keyboard bottom surface 36 is visible as shown in FIG. 8, to the open 7th keyboard position 56, where keyboard top surface 35 is visible and keyboard bottom surface 36 is not visible as shown in FIG. 10.

FIG. 11 is a schematic top view of an alternative example of flippable keyboard 3 of FIG. 4 incorporating a Touchpad 58. With reference to FIG. 11, an input device Touchpad 58 is embedded in flippable keyboard 3 positioned medially near front edge of flippable keyboard 3. Touchpad 58, with its associated hardware and software components, functions both as a cursor-pointing device and a scroll control device. Also visible in FIG. 11 are 1st table depression 4, 2nd table depression 5, groove pin 23, and groove 22, the mechanisms for these parts are similar to those described in FIG. 1 and FIG.3.

FIG. 12 is a partial isometric view right side of foldable table apparatus 1 showing in detail how groove pin 23 is secured inside groove 22 (only one side of flippable keyboard 3 is shown). Flippable keyboard 3 may be flipped to an open and closed position by means of groove pin 23 that is shaped in such a way that it is able to slide freely along groove 22 without being snapped off in place. The shape of groove 22 may be formed, cut or preferably molded into foldable table apparatus 1. Alternatively, groove 22 may be formed as a separate part, such as a pin guide rail 21, which is subsequently attached to foldable table apparatus 1 as shown in FIG. 12. Groove 22 may be constructed from a stamped sheet of metal fixed within foldable table apparatus 1. When flippable keyboard 3 is rotated to an open or closed position, groove 22 slidably receives groove pin 23 as groove pin 23 slides from one end to the opposite end of pin guide rail 21 similar to that shown in FIG. 9.

FIG. 13 is a top view of a further alternative example of the flippable keyboard 3 of FIG. 11 incorporating a Trackpoint style device 70. Located at essentially the center of flippable keyboard 3 is Trackpoint device 70. Trackpoint device 70 and its associated circuitry and software may function as a cursor-pointing device or as a window content scroll control device of flippable keyboard 3. It consists of a visible finger pad and an embedded four strain gauges that serve as directional pressure sensitive sensors similar in function to the IBM Trackpoint device typically found on the keyboards of IBM branded laptop computers. Shown in hidden outline in FIG. 13 are the embedded electronic devices that include a wireless adapter 60 to enable flippable keyboard 3 to communicate wirelessly with the host PC or with other electronic devices within one or more established wireless networks, an internal communications antenna 62 to transmit and receive RF signals, power supply regulator 61, rechargeable battery 64 to supply power to flippable keyboard 3 and foldable table apparatus 1, data bus/bridge controller chip 65 to enable the keyboard data to communicate with the host PC through wireless adapter 60, mini hard drive 66 for storing data, keyboard and pointing device chip 67, memory chip 68 for storing data or program instructions in the computer and for retrieving them, and microphone/audio chip 69. The addition of embedded devices within flippable keyboard 3 enhances its functionality and its wireless capability to the host system. The embedded devices may function as peripheral devices connected via a USB or network connection to the host PC and under the control of the host PC. Flippable keyboard 3 and its peripheral devices may communicate to the host PC, PDA, or computer device using a wired or wireless connection. With the addition of a built-in CPU and its associated circuitry within foldable table apparatus 1, the embedded devices and CPU may be integrated into an autonomous computing device with wired or wireless connectivity to the other computing devices on a network. Rechargeable battery 64 provides a suitable voltage and current for flippable keyboard 3 and other peripheral electronic devices placed within foldable table apparatus 1. The battery may be recharged by an AC/DC recharger unit or from a powered USB connection cable. In addition, an AC/DC power adapter attached to a wall receptacle may supply power. Mini hard drive 66 may have a typical capacities range for holding data from 1.5 GB to 4 GB and a size of 1-2 inches across. It may be adapted to store data files over a USB and wireless connection.

The movable portion is attached to keyboard table enclosure 341 via support arm pin 347 while the fixed portion is attached to foldable keyboard table 340.

FIG. 84 is a schematic side view of the foldable keyboard table 340 of FIG. 83 as it is fully extended from its upright storage position. As shown in FIG. 84, foldable keyboard table 340 is extended in one motion essentially along extending direction arrow 352 effecting keyboard table pin 344 to slide along groove 343 and to move from one end to the opposite end of groove 343. In FIG. 84, foldable keyboard table 340 and supporting arm 345 have reached their maximum extendable length as the upward movement of grooved plate 342 is momentarily stopped by keyboard enclosure pin 350 as it comes in contact with protruding end of grooved plate 342, and keyboard table pin 344 that rests on opposite end of groove 343. The upward movement of supporting arm 345 is also stopped as support arm pin 347 is in contact with support arm stop 348 preventing supporting arm 345 from further movement.

FIG. 85 is a schematic side view of the foldable keyboard table 340 of FIG. 83 as it is rotated to an open horizontal position. From the maximum extendable lengths of foldable keyboard table 340 and supporting arm 345 in FIG. 84, foldable keyboard table 340 is rotated essentially along table rotation direction arrow 354 to an open horizontal position as supporting arm 345 slides down from support arm stop 348 essentially along support arm drop direction arrow 353. Grooved plate 342 and groove 343 maintain their positions as in FIG. 84 relative to keyboard enclosure pin 350 and keyboard table pin 344 respectively. Support arm notches 349 may be moved back and forth at this position via support arm pin 347 to adjust the horizontal level of foldable keyboard table 340.

FIG. 86 is a schematic front view of the foldable keyboard table 330 of FIG. 82. With reference to FIG. 86, foldable keyboard table 330 rests on supporting arm 334 in an open horizontal position with supporting arm tip 339 shown in hidden outline at the bottom of foldable keyboard table 300. Visible in FIG. 86 is table enclosure notch 335 that serves as entry and exit area for foldable keyboard table 330 and supporting arm 334. Shown in hidden outline is grooved plate 336 that is attached to supporting arm 334 via support arm pivot rod 333.

FIG. 87 is a schematic front view of the foldable keyboard table 340 of FIG. 85. With reference to FIG. 87, foldable keyboard table 340 rests on supporting arm 345 in an open horizontal position. Also shown is table enclosure notch 356 that serves as entry and exit area for foldable keyboard table 340 and supporting arm 345. Keyboard table pin 344, which is attached to foldable keyboard table 340, is shown in hidden outline. Also shown in hidden outline is grooved plate 342 on respective left and right sides of foldable keyboard table 340 in contact with keyboard enclosure pin 350.

FIG. 88 is a side view of the keyboard table 300 of FIG. 72 as applied to a passenger seat. With reference to FIG. 88, keyboard table 300 and hinged display enclosure 305 are mounted in a separate enclosure, detachable compartment 357, which may be mounted by screws or hang bars to the rear of forward seat 359. Detachable compartment 357 may be disengaged from forward seat 359. The electronics and hardware for the computer may be housed in forward seat 359.

FIG. 89 is a side view of the retractable keyboard table 312 of FIG. 75 as applied to a passenger seat. With reference to FIG. 89, retractable keyboard table 312 is contained in a separate enclosure, detachable compartment 360, while hinged display enclosure 305 is built-in in forward seat 361. Detachable compartment 360 may be disengaged from forward seat 361. The electronics and hardware for the computer may be housed in forward seat 361. It should be noted that in case of an accident or a sudden stop and the passenger or user slumps into retractable keyboard table 312, the latter would only retract or draw back into cavity of detachable compartment 360 thereby preventing serious damage to the passenger or user.

FIG. 90 is a side view of the hinged keyboard table 322 of FIG. 78 as applied to a passenger seat. Hinged keyboard table 322 and associated display enclosure 305 are mounted to the rear of forward seat 321. Also shown is hinged display enclosure 305 built-in in forward seat 321.

FIG. 91 is a side view of the foldable keyboard table 340 of FIG. 85 as applied to a passenger seat. Both keyboard table enclosure 341 and hinged display enclosure 305 may be mounted to the rear of forward seat 358, the former houses foldable keyboard table 340.

FIG. 92 shows a block diagram of a “System on a Chip” module of a keyboard table enclosure 368 embedded on a foldable table apparatus 420. The “System on a Chip” includes the following components: internal memory 364, wireless adapter 365, keyboard and pointing device 366 and external memory 367 all located within keyboard table enclosure 368 of foldable table apparatus 420. The components contained within the “System on a Chip” module may be located separately within either the keyboard enclosure or display enclosure, or external to both. In such an arrangement, the electronics associated with each component may be mounted to a single printed circuit board to save manufacturing costs and to improve reliability. The CPU and video components are not shown within the block diagram of FIG. 92. The CPU and video components are located elsewhere—within the display enclosure or external to both display enclosure and keyboard enclosure. The primary function of wireless adapter 365, in case of a wireless keyboard, is to enable the computer keyboard data and the “System on a Chip” module data to communicate wirelessly with the host PC or with the other electronic devices within one or more established wireless networks. The primary function of data bus/bridge, in case of a wireless keyboard, is to enable the computer keyboard data and the “System on a Chip” module data to communicate, through the embedded wireless adapter 365, with the host PC or other electronic devices within one or more established wireless networks.

FIG. 93 is a block diagram of the primary functions of central server computer 370. Central server computer 370 is essentially a high-performance computer with the following primary functions:

Data Repository 372—central repository and control access for resources such as data files, emails, multimedia files, etc.

Gateway 371—network gateway for Internet connections; and management of Wi-Fi network infrastructure

Session Manager 373—management of client terminal sessions

Fail-safe 374—management of fail-safe mechanisms of the system Accounting/Billing/Auditing 375—implementation of the usage accounting and auditing functions for billing purposes

Security 376—management of security by incorporating appropriate authentication and authorization measures; and guarding against network intrusion attacks and viruses

The central server computer 370 typically runs a high-end version of a server operating system such as Windows Server 2003 Data Center Edition, or various versions of UNIX. It also uses system management software such as IBM's Tivoli, or HP's Insight Manager to monitor the health of all computers and devices on Wi-Fi computer network.

FIGS. 94-102 are block diagrams of the architectural approaches in the implementation of a computer network on an aircraft utilizing a wireless network, such as for example, a Wi-Fi network as the physical transport. The architectural approaches described in FIGS. 94-102 all depend (in varying degrees) on the services provided by central server computer 370. A common feature to such architectural approaches is the presence of a high-performance central server computer 370. The approaches differ only in the configuration of the client computers, as central server computer 370 is adaptable to various client computer configurations.

Accordingly, FIG. 94 is a block diagram of the composition of a “smart client” 380 configuration. “Smart client” 380 is composed of the following technology stack: hardware abstraction layer 383, operating system layer 382, and application layer 381. Hardware abstraction layer 383 also includes low-level device drivers that interface with the physical hardware. Operating system layer 382 includes software that runs and controls the devices installed on the system; it manages the graphical and input output functions of the computer; it provides services (such as printing, multimedia, graphics, etc.) to the applications that the user runs. Application layer 381 maps to application software typically used, such as Microsoft Word, Microsoft Excel, Microsoft Internet Explorer, etc. In the “smart client” 380 configuration, the client computer is practically a laptop-class computer: it has a hard drive, processor, memory, keyboard and pointing device, Wi-Fi adapter, display card and associated display device, operating system, and locally installed application software. This hardware configuration is similar to a Tablet PC. “Smart client” 380 computer can make a Wi-Fi connection 384 to central server computer 370 via Wi-Fi access points installed at strategic locations inside the airplane. The “smart client” 380 computer is similar in capabilities to a laptop or desktop computer: the user can view, edit, and delete documents, and save them either to the local hard drive or to the network accessible storage on central server computer 370; the user can stream multimedia files (such as movies) hosted on central server computer 370, perhaps on a pay-per-view basis; the user can play interactive games; the user can surf the Internet, send email, chat, upload/download files to or from the Internet hosts. The “smart client” 380 configuration may be distinguished from the other configurations in its ability to function (sans network connectivity) even when disconnected from central server computer 370 because the “smart client” 380 computer is essentially a standalone PC.

FIG. 95 is a block diagram of the composition of a “dumb terminal” 390 client. With reference to FIG. 95, “dumb terminal” 390, which communicates to central server computer 370 through Wi-Fi connection 393, is composed of the following technology stack: hardware abstraction layer 392 that is made up of all hardware components (such as Wi-Fi circuitry) and their requisite device drivers, and terminal client software 391 that acts as a rudimentary operating system. Terminal client software 391 can be compared to a web browser in that it doesn't perform any processing logic. “Dumb terminal” 390 merely displays output of applications running remotely on central server computer 370, and accepts inputs coming from the user and forwards them to the remotely running application. In the “dumb terminal” computer configuration, the client computer is an inexpensive network computer. Basically, “dumb terminal” 390 client computer will only include a boot-enabled Wi-Fi adapter, a processor, memory, keyboard and pointing device, and a display card and associated display device. It will boot from central server computer 370, through standard network boot protocols. While it is possible to outfit “dumb terminal” with a hard drive for local data storage, this is not normally done. During the boot process, “dumb terminal” 390 downloads the operating system image to its main memory and then runs it, effectively booting operating system locally. Typically, “dumb terminal” 390 runs applications on central server computer 370, with just the user interface displayed on “dumb terminal's” 390 screen; every user action such as entering commands are buffered and then sent back to the application running on central server computer 370; the application in turn, interprets command and may then update the user interface displayed on screen of “dumb terminal” 390. “Dumb terminal” 390 client computer functions similarly like the “smart client” 380 client computer except the former typically runs slower since all applications software run on central server computer 370 and every action made by the user against the user interface may require a round-trip to central server computer 370. This drawback makes “dumb terminal” 390 completely dependent on central server computer 370. Without central server computer 370, “dumb terminal” 390 will not function.

FIG. 96 is a block diagram of the compositions of hybrid with expansion module 404 client and basic hybrid configuration 400 client. Hybrid with expansion module 404 client is essentially similar to “smart client” 380 computer (shown in FIG. 94). Both have the same technology stack that function similarly. However, hybrid with expansion module 404 client has an additional expansion module 406 attached to its expansion slot 405, and the terminal client software 409 (unused). In FIG. 96, have client may communicate to central server computer 370 through wireless connection 412. As shown in FIG. 96, basic hybrid configuration 400 client may communicate to central server computer 370 through wireless connection 411. It is essentially similar to “dumb terminal” 390 client computer and is composed of the following technology stack—hardware abstraction layer 403 that is made up of all hardware components (such as Wi-Fi circuitry) and their requisite device drivers, and terminal client software 402 that acts as a rudimentary operating system. In the “hybrid” configuration, the client computer is initially configured similar to a “dumb terminal” 390. However, basic hybrid configuration 400 client computer has an expansion slot 401 that accommodates an expansion module 406. By attaching expansion module 406 into expansion slot 401 basic hybrid configuration 400 is automatically upgraded to become a “smart client” 380. The “hybrid” client configuration combines the capabilities of “smart client” 380 and “dumb terminal” 390 configurations.

FIG. 97 is a block diagram of a “computer-on-a-card” module 434 that is used in the keyboard 430/display 432 system. The system can be manufactured in a highly modular fashion, with each of the components—keyboard 430, display 432, and “computer-on-a-card” module 434 (as well as other components such as a DVD-ROM drive)—being fabricated or outsourced separately. The “computer-on-a-card” module 434 is the result of the integration of the core electronics of keyboard 430/display 432 system into a single, integrated module such as CPU 435, memory 438, data store 436 (hard drive or non-volatile memory), display adapter 437, audio adapter 440, input/output (I/O) adapter 439, and Wi-Fi adapter 44.

FIG. 98 is a block diagram of a “computer-on-a-card” module 434 attached to the expansion slot 431 of keyboard 430. When assembled, “computer-on-a-card” module 434 may simply be attached to either keyboard 430 or display 432, through expansion slots 431 (FIG. 98) and expansion slot 433 (FIG. 99). Expansion slot electronics can be accommodated either within display housing, within keyboard housing, or within housing for both components. This modularity facilitates maintenance and upgrade of system. In the configuration of FIG. 98, display 442 need not have expansion slot electronics.

FIG. 99 is a block diagram of a “computer-on-a-card” module 434 attached to the expansion slot 433 of display 432. In the configuration of FIG. 99, keyboard 450 need not have expansion slot electronics.

FIG. 100 is a block diagram of the direct connectivity option for linking the keyboard to the display. There are two connectivity options for linking the keyboard to the display: direct or indirect. Physical cables (wired connection 462) can accomplish a direct connection between keyboard 461 and display 460. A direct connection between keyboard 464 and display 463 can also be accomplished without the need for physical cables (wireless connection 465) using a suitable wireless technology such as Bluetooth or infrared. With direct connection option, the keyboard-and-display system functions as a unit and do not depend on the external components to establish a communication link.

FIG. 101 is a block diagram of the indirect connectivity option for linking the keyboard to the display. Establishing an indirect connection between keyboard 471 and display 470 requires the participation of central server computer 473 and the presence of Wi-Fi hardware on both keyboard 471 and display 470. In this configuration, keyboard 471 and display 470 are considered independent devices that have been “paired” dynamically. Keyboard 471 connects to its complementary device (i.e. a display 470) by sending a “pairing” request via a Wi-Fi connection 475 to central server computer 473. Central server computer 473 then dynamically searches for appropriate complementary device, and upon finding one, performs a “pairing” operation that establishes a virtual connection 472 between keyboard 471 and its complementary display 470. Conversely, the same process can also be initiated by display 470, as follows: a display sends a “pairing” request via a Wi-Fi connection 474 to central server computer 473 that then dynamically searches for and assigns an appropriate keyboard 471 to display 470. This connection option requires that both keyboard and display have an integrated Wi-Fi hardware, and both should have the capability to establish a connection with central server computer 473.

FIG. 102 is a block diagram showing the integration to an existing wireless networking infrastructure 482. If a wireless networking infrastructure 482 (for example, Connexion) is already in place inside the aircraft, central server computer 480 can be configured to seamlessly interface with it by adapting the same (or compatible) hardware, software, and communication protocols that it uses. Such interfacing can be accomplished by a “middleware” 481—that can be a hardware device, a software application, or both. “Middleware” 481 acts as a “translator” and enables central server computer 480 to communicate efficiently with existing wireless networking infrastructure 482. Keyboard-and-display units 484 communicate with central server computer 480 through Wi-Fi connections 483.

FIG. 103 is a cross sectional view of table top 600 with an embedded keyboard 602, a variation of a section taken along lines 30-30 of FIG. 28 and lines 31-31 of FIG. 29 in a closed cover position. Keyboard cover 604 protects embedded keyboard 602 when the latter is not in use or in a closed position and permits table top surface 610 above embedded keyboard 602 to retain its functionality as a table for placing items on and bearing their weights. Keyboard cover 604 is attached to a second smaller cover segment 612 via pivot pin 606 that in turn is attached to hinge pin 608. Pivot pin 606 and hinge pin 608 permit keyboard cover 604 and second smaller cover segment 612 to be lifted and rotated in such a manner that keyboard cover 604 hangs off side of table. It should be understood that hinge pin 608 may be attached to embedded keyboard 602 as shown in FIGS. 103-104 or may be attached to a portion of table top 600. Hinge pin 608, which secures keyboard cover 604, may also be located to the left or right side of embedded keyboard 602 rather than being positioned near the bottom of embedded keyboard 602 as shown in FIGS. 103-104.

FIG. 104 is a cross sectional view of table top 600 of FIG. 103, a variation of a section taken along lines 30-30 of FIG. 28 and lines 31-31 of FIG. 29 in an open cover position. Pivot pin 606 and hinge pin 608 permit keyboard cover 604 and second smaller cover segment 612 to be lifted and rotated in such a manner that keyboard cover 604 hangs off the side of the table from its phantom line representation of table surface 708 as shown in FIG. 104. It may be expected that in the open cover position 614, keyboard cover 604 may rest on the lap or waist of the user. The open cover position 614 permits a user to have unencumbered access to embedded keyboard 602. The keyboard arrangement depicted in FIGS. 103-104 is useful if keyboard cover 604 is on a table of limited depth and it is not practical to pivot keyboard cover 604 away from the user in the manner depicted in FIGS. 30-31.

FIGS. 105-113 depict an example of a swivel 180-degree twisting keyboard panel embedded within a foldable table apparatus, in accordance with a further preferred embodiment of the present invention. Such an arrangement presents a clean and esthetically pleasing foldable table apparatus when the keyboard panel is in the closed position. The keyboard panel is also firmly secured when it is flipped and rotated about 180 degrees to its open position.

Accordingly, FIG. 105 is a front view of an example of a foldable table apparatus 620 incorporating a swivel 180-degree twisting keyboard panel 624 in an open position. In the figure, twisting keyboard panel 624 is shown in an essentially vertical position similar to the isometric view depicted in FIG. 107. Swivel hinge 626 permits twisting keyboard panel 624 to rotate or pivot essentially along swivel hinge rotation axis 627, 628. It should be understood that keyboard keys 629 face upside down and are not visible when twisting keyboard panel 624 is in the closed position as shown in FIG. 106. In FIG. 105, twisting keyboard panel 624 is swivelly attached to lower table panel 622 by means of swivel hinge 626 the same as in further examples of a twisting keyboard panel that is attached to a lower table panel within the scope of the present invention.

FIG. 106 is an isometric view of the foldable table apparatus 620 of FIG. 105 in a closed position. Securing arms 20 attaches to lower table panel 622 and permits the latter and twisting keyboard panel 624 to be folded in an upright position. In keeping with the present invention, tray stop 7 may be incorporated on both the top surfaces of twisting keyboard panel 624 and lower table panel 622. The swivel 180-degree twisting keyboard movement is accomplished by means of swivel hinge 626. Swivel twisting hinges are commonly used in attaching the LCD viewfinders of digital cameras, digital video camcorders, or cellular phones to the main electronics housing or keypad. Samsung SGH-P400 DigitAll Twist GSM cell phone, for example, uses such a swivel twisting hinge.

FIG. 107 is an isometric view of foldable table apparatus 620 in which twisting keyboard panel 624 is pivoted about swivel hinge 626 to an essentially vertical position from the flat closed keyboard position as shown in FIG. 106.

FIG. 108 is an isometric view of foldable table apparatus 620 in which twisting keyboard panel 624 is pivoted about swivel hinge 626 in a clockwise fashion from the essentially vertical keyboard position of FIG. 107. The keyboard keys of twisting keyboard panel 624 remain in an inverted position in FIGS. 107-108.

FIG. 109 is an isometric view of foldable table apparatus 620 in which twisting keyboard panel 624 is further rotated about swivel hinge 626 in a clockwise fashion and lowered onto lower table panel 622 until the keyboard panel is oriented to the user in a normal flat manner relative to the somewhat vertical keyboard panel position as depicted in FIG. 108. In FIG. 109, keyboard keys 629 are in an open and flat position. Keyboard keys 629 may either protrude or be recessed relative to the keyboard panel surface. When keyboard keys 629 are recessed, a food tray may be placed on the keyboard panel surface without accidentally pressing on the keyboard keys. The upper twisting keyboard panel 624 may be securely attached to the lower table panel 622 by means of mechanical hooks and table latches, spring tensioning in swivel hinge 626, molded indents and alignment guides, magnetic attraction, and the like. A secured attachment between twisting keyboard panel 624 and lower table panel 622 is necessary to avoid the noise caused by the vibration of panels 622, 624 during turbulence and during take-off and landing of the aircraft. Further, a secured attachment of panels 622, 624 avoids accidental slippage of food tray while passengers are eating, beverage spills while they are consuming refreshments, and spills from passengers bumping foldable table apparatus 620 while entering and exiting their seats.

FIG. 110 is an isometric view of an alternative example of a foldable table apparatus in which swivel hinge 636 is mounted at the front as twisting keyboard panel 634 is rotated about in an essentially vertical keyboard position. Swivel hinge 636 is mounted at the front sides of twisting keyboard panel 634 and lower panel 632. When swivel hinge 636 is mounted at the front of foldable table apparatus 630, it is less likely that rotating twisting keyboard panel 634 will cause it to meet the rear of the forward seat on which securing arms 20 are mounted. In FIG. 110, twisting keyboard panel 634 can be rotated sideways via swivel hinge 636 essentially along swivel hinge rotation axis 631.

FIG. 111 is an isometric view of a foldable table apparatus in which swivel hinge 639 is mounted to the right as twisting keyboard panel 638 is rotated about in an essentially vertical keyboard position. Swivel hinge 639 is mounted to the right sides of twisting keyboard panel 638 and lower panel 637. When swivel hinge 639 is mounted at the side of foldable table apparatus 635, it is less likely that rotating twisting keyboard panel 638 will cause it to meet the rear of the forward seat on which securing arms 20 are mounted. In FIG. 111, twisting keyboard panel 638 can be rotated sideways via swivel hinge 639 essentially along swivel hinge rotation axis 633.

FIG. 112 is an isometric view of an example of a foldable table apparatus incorporating table ledge 662 and twisting keyboard panel 661. Swivel hinge 663 is mounted medially on left side of keyboard panel 661 and medially on left side of foldable table apparatus 660. Below table ledge 662 is a recessed table top surface 671 that receives keyboard panel 661 in its horizontal position (either closed or open position). Table ledge 662 permits keyboard panel 661 to fit flush with the thicker back portion of foldable table apparatus 660. The keyboard panel being used may be slightly smaller than the keyboard panel of FIG. 111. In FIG. 112, keyboard panel 661 can be rotated about sideways by means of swivel hinge 663 essentially along swivel hinge rotation axis 664 to an essentially vertical manner to place keyboard panel 661 in an open or closed position on recessed table top surface 671. To move keyboard panel 661 to its closed position, twisting keyboard panel 661 is rotated essentially 180 degrees about swivel hinge 663 and lowered onto foldable table apparatus 660 to a flat position similar to the twisting keyboard panel 624 shown in FIG. 106.

FIG. 113 is an isometric view of an example of a two-piece foldable table apparatus 670 showing table ledge 662 and twisting keyboard panel 667. As shown in FIG. 113, two-piece foldable table apparatus 670 includes a 1st table piece 665 that is connected to 2nd table piece 666 via a pair of table hinges 621. Swivel hinge 668 is mounted medially in front of 2nd table piece 666 and medially in front of twisting keyboard panel 667. Table ledge 662 has two primary functions: 1) it forms a recessed table top surface 671 that receives twisting keyboard panel 667, in its closed or open horizontal position, and 2) it facilitates efficient functioning of table hinge 621 by leveling the hinged edges of 1st table piece 665 and 2nd table piece 666. It should be noted that table hinge 621 appears more esthetically pleasing and functions to fold both table pieces 666, 665 if both hinged edges are flushed and of the same thickness. In FIG. 113, twisting keyboard panel 667 can be rotated about sideways by means of swivel hinge 668 essentially along swivel hinge rotation axis 669 to an essentially vertical manner to place twisting keyboard panel 667 in an open or closed position on recessed table top surface 671.

FIG. 114 is a perspective view of an example of a foldable table apparatus 644 upon which keyboard pattern 643 is projected 646. Keyboard pattern 643 is generated and projected 646 onto the flat tabletop surface of foldable table apparatus 644 by using the Canesta keyboard Perception Chipset that is especially suited to the low ambient light of some aircraft cabin environments. The use of such a system to input data to a computer ensures that the conventional foldable table apparatus 644 does not require replacement and remains easy to clean. The Canesta keyboard Perception Chipset is contained within pivoting housing 641, the latter contains a Canesta Sensor Module, Light Source, and Pattern Projector (for example, SM-CK100, IR-CK100, PP-CK100 chipset modules from Canesta or their functional equivalents). The power supply and data communication to and from Canesta chipset within pivoting housing 641 are provided by a wired connection to display screen 640 and its associated electronics. The orientation of pivoting housing 641 may be rotated to project a legible keyboard pattern 643 with each adjustment positions of foldable table apparatus 644 and display housing 648. Display screen 640 may also be pivoted essentially along display rotation direction arrow 642 to adjust for the reclining seat position of the passenger seated in front.

FIG. 115 is an isometric view of an example of a foldable table apparatus of the type shown in FIG. 19 incorporating an embedded key FrogPad style keyboard 656. Also shown in FIG. 115 is the attached keyboard insert module 652 that contains a beverage holder area 654 and an embedded key FrogPad style keyboard 656 typically associated with FrogPad, Inc. The easy to replace keyboard insert module system permits passengers to use special keyboard types such as a FrogPad style keyboard 656 within foldable table apparatus 650. The aforementioned keyboard insert module may be customized for left or right handed individuals and may be developed for other languages or for special functions. In some instances, fonts and software specific to the keyboard may be embedded within a keyboard insert module or keyboard packaging. Should a keyboard insert module become defective or dirty, it may be replaced quickly and conveniently by the passenger or the aircraft attendant. There is no need for the maintenance crew to be scheduled for a service call, thus, saving the airline carrier considerable time and costs. As with any of the keyboard devices depicted in the present invention, input and output data to and from the keyboard may be communicated to the CPU or computer using a wired or wireless connection. Keyboard insert module 652, for example, typically contains all keyboard electronics, power supply, and peripheral communications circuitry to establish wired or wireless contact with the passenger's associated computer processor, display, and/or server.

FIGS. 116-118 illustrate an example flippable display panel with an embedded display screen. Such an example is ideal in areas, especially outdoors, where access to a display screen is frequent and needs to be protected against damage, such as in factories, elevators, airports, schools, banks, malls, and similar establishments. The display screen is protected against damage and kept clean because it is easily returned to a closed position after use.

Accordingly, FIG. 116 is a schematic side view of an example of a display panel enclosure 680 incorporating a flippable display panel 672 with an embedded display screen 674 progression as it is rotated from its closed vertical position to a horizontal position. As shown in FIG. 116, flippable display panel 672 is flipped and rotated about groove pin 673 essentially halfway to a horizontal position as indicated by phantom line representation of flippable display panel 710 in downward motion essentially along rotation direction arrow 675, therefrom rotated further downward to a horizontal position essentially along rotation direction arrow 676. In this position, flippable display panel 672 is securely attached to display panel enclosure 680 via groove pin 673.

FIG. 117 is a schematic side view progression of the display panel enclosure 680 of FIG. 116 showing flippable display panel 672 as it is rotated about and moved from one end to the opposite end of grove 681.

Rare earth magnets 428 are also embedded within the table apparatus 425 in such a manner as to align with the rare earth magnets 429 of the keyboard apparatus 426. Thus, the keyboard apparatus 426 is magnetically attracted and held stationary when placed on the top of table apparatus 425. The keyboard apparatus 426 communicates wired or wirelessly with a nearby access point or through a USB connector. The design permits the keyboard apparatus 426 to stay secure should the flight encounter turbulence.

FIG. 153 shows the architecture of an Advertisement Targeting System adapted for use in the system of the present invention. An airline can operate an Advertisement Targeting System 1310 aboard an aircraft 1330 to deliver targeted advertisements to aircraft's passengers via the keyboard and display apparatus 1350 accessible to each passenger. The targeted advertisements produced by the Advertisement Targeting System 1310 are typically delivered to the keyboard and display apparatus 1350 using a middleware Application Programming Interface (API) whose components are shared by the Advertisement Targeting System 1310 and the keyboard and display apparatus 1350. The middleware API 1332 which is installed close to the Advertisement Targeting System 1310, and the middleware API 1346 which is installed with the keyboard and display apparatus 1350 typically implement optimized functions for delivering targeted advertisements to the keyboard and display apparatus 1350.

The aircraft 1330 maintains a User Profiles 1312 database containing detailed information about its passengers. The aircraft 1330 also maintains an Ad (i.e. Advertisements) Pool 1314 containing advertisements that are generated in-house by the airline company, and advertisements that are outsourced from third party companies such as Third Party Ad Provider 1340. The User Profiles 1312 database and the Ad Pool 1314 are inputs to the Advertisement Targeting Engine 1326, which implements the logic for selecting advertisements that closely match the interests of a given passenger.

The aircraft 1330 may grant permission to a Third Party Ad Provider 1340 to deliver targeted advertisements directly to the aircraft's 1330 passengers. The Third Party Ad Provider 1340 typically operates its own Advertisement Targeting System 1342. To facilitate the delivery of targeted advertisements, the Third Party Ad Provider 1340 typically employs middleware API 1344 which is installed close to the Advertisement Targeting System 1342, and middleware API 1348 which is installed with the keyboard and display apparatus 1350. The middleware API 1344 and middleware API 1348 ensure data compatibility between the data format used by the Third Party Ad Provider 1340 and the data format that is understood by the keyboard and display apparatus 1350.

The Third Party Ad Provider 1340 typically maintains its own Ad Pool 1338 and it may also maintain its own User Profiles 1334 database. The Third Party Ad Provider 1340 typically does not have detailed profile information about the aircraft's 1330 passengers, as a result the advertisements that the Third Party Ad Provider 1340 delivers directly to the aircraft's 1330 passengers may not accurately match the passengers' interests. The User Profiles 1334 database and the Ad Pool 1338 are inputs to the Ad Targeting Engine 1336, which implement the logic for selecting advertisements that closely match the interests of passengers. The Third Party Ad Provider 1340 may also deliver targeted advertisements to the aircraft 1330 for redistribution by the latter to its passengers. In this scenario, the aircraft 1330 uses the Third Party Ad Provider 1340's middleware API 1344 to receive advertisements which the aircraft 1330 may then store in its Ad Pool 1314.

The targeted advertisements delivered by the aircraft 1330 and/or Third Party Ad Provider 1340 to the keyboard and display apparatus 1350 are typically displayed to the passenger using suitable user interface technologies such as HTML, Macromedia Flash, Portable Document Format (PDF), and the like. The User Interface Components 1354 that are installed with the keyboard and display apparatus 1350 are responsible for displaying the targeted advertisements to the passenger. The User Interface Components 1354 typically capture statistical data pertaining to the display of the advertisement, such as the time the passenger spends viewing an advertisement, the time it takes to browse through a list of advertisements, the time it takes for the passenger to purchase the advertised product or service, and other related metrics. The User Interface Components 1354 typically communicates the statistical data that it captures to the Advertisement Targeting System 1310, using middleware API 1346 and middleware AP 1332.

When a passenger using the keyboard and display apparatus 1350 responds to a targeted advertisement by executing an action such as clicking on the Uniform Resource Locator (URL) associated with the targeted advertisement, the passenger is typically directed to an E-Commerce System 1360, which is a system that facilitates the online purchase of products and services. The E-Commerce System 1360 may be operated by the aircraft 1330, or the E-Commerce System 1360 may be operated by a third party company, for example the seller or provider of the product or service being advertised. The E-Commerce System 1360 typically employs a middleware API 1356 to facilitate communication with the keyboard and display apparatus 1350 and the Advertisement Targeting System 1310 operated by the aircraft 1330. The Order Processing System 1358 is responsible for processing the purchase transactions that may be initiated by passengers using the the Front-end Trading System 1350.

Typically, the Advertisement Targeting System 1310, the User Interface Components 1354, the Order Processing System 1358, and the various middleware API's work together to facilitate purchase transactions, to perform business-related auditing, to gather statistical information about the purchasing behavior of passengers, and to perform other related functions.

FIG. 154 shows the internal structure of the Advertisement Targeting System. The Advertisement Targeting System 1310 typically uses a User Profiles 1312 database and an Ad Pool 1314 as inputs. The User Profiles 1312 database contains detailed information about passengers and their respective interests/preferences, demographics, purchasing history, and any other information that the owner of the Advertisement Targeting System 1310 consider relevant. A data record in the User Profiles 1312 database may represent a single person or entity, or a group of persons or entities categorized together based shared characteristics.

The Ad Pool 1314 is a database of advertisements containing information about the specifications of a product or service, purchasing information, images, referral-tracking information, and other merchandise-related information. The User Profiles 1312 database and the Ad Pool 1314 are typically generated and maintained by the owner of the Advertisement Targeting System 1310. The owner of the Advertisement Targeting System 1310 may also obtain the contents of the User Profiles 1312 database and the Ad Pool 1314 from third party companies such as market research firms, advertising firms, and the like.

The output of the Advertisement Targeting System 1310 is a set of Targeted Ads 1324 that match the interests of a given passenger. The Targeted Ads 1324 are typically packaged in a suitable data exchange format, such as XML. At the core of the Advertisement Targeting System 1310 is the Advertisement Targeting Engine 1326, which can be visually depicted as a funnel. A large set of potential advertisements retrieved from the Ad Pool 1314 are fed to the Advertisement Targeting Engine 1326. The Advertisement Targeting Engine 1326 gradually narrows down the set of advertisements by applying filtering and scoring rules to the set of advertisements until only a small set of advertisements is left.

The Advertisement Targeting Engine 1326 executes several steps to generate Targeted Ads 1324 that match the interests of a given passenger. The Filtering 1316 step quickly removes advertisements from the initial set of potential advertisements. In this step the Advertisement Targeting Engine 1326 applies broad rules, for example a date range or demographic criteria such as the gender or age of the target market for the advertisements. The Scoring 1318 step involves the application of computational methods, business rules, and other criteria, to evaluate how closely an advertisement matches the interests of a given passenger. During this step a score is associated with each advertisement based on the results of the aforementioned computational methods/business rules. An example of a business rule used during this step is the assignment of a higher score to advertisements made by a preferred company.

The Select Winning Ads 1320 step involves the application of further business rules against the set of advertisements generated by the previous steps, in order to rank the set of advertisements according to some criteria. An example of a business rule used during this step is to select the top N paid advertisements that maximize profits for the owner of the Advertisement Targeting System 1310. The Record History 1322 step involves the recording of the final output of the Advertisement Targeting Engine 1326 in the User Profile record of a given passenger. This information is typically used during subsequent executions of the Advertisement Targeting Engine 1326, for example to exclude advertisements that have been previously delivered to a given passenger.

FIG. 155 shows a representation of a desktop user interface 1150 presented to a typical passenger, for example, on display screen 15 of FIG. 1. During and after boarding of the passenger vessel, each seat's associated display screen may show the appropriate seat number and designated passenger name 1152 to avoid confusion and facilitate boarding and navigation within the vessel. A variety of general and targeted services are available to the passenger. For example, they may choose to browse and order items by clicking on duty free shopping icon 1154 to access the duty free catalog. Similarly, the user may listen to music or read online magazines 1156, watch an assortment of movies 1158, listen to radio or TV programs 1160, obtain flight info 1162 such as travel time remaining, obtain access to free software and services 1164 provided by the airline or software developers, access the internet 1166, compose and send email 1168, use software applications 1170 to open, edit, and save work files, access premium or prepaid services 1172, play online games 1174, and the like. General or targeted advertisements 1178 offering products or services may be presented to each passenger during the course of their flight. If the passenger is carrying a device with data files or flash memory, the device may be connected to the terminal's host electronics via a wired or wireless connection. For example, if a flash memory device is connected to the keyboard USB jack, a USB device icon 1176 will appear on the desktop allowing the user to access stored files as well as to save data to the flash memory device.

FIG. 156 shows a preferred embodiment of a user interface for organizing and presenting archive data associated with users of the passenger keyboard and display apparatus of the present invention. The user interface window 1200 uses a graphical user interface component commonly known as TreeView component 1202 to represent the hierarchical organization of archive data associated with users of the keyboard and display apparatus. The TreeView component 1202 uses a hierarchical arrangement of icons (such as folder icons, document icons, and the like) to represent the categorization of archive data into groups. The TreeView component 1202 uses folder icons to represent groups of data, and document icons to represent specific data items such as text files, audio files, binary files, and the like. Typically, the archive data is categorized by seat number, by flight number, and by month and year. However, other methods for organizing and presenting archive data may also be used. It should be noted that the information presented in the user interface window 1200 is accessible only to authorized personnel, such as members of an airline's Flight Operations group.

The SEAT 30C folder icon 1204 represents archive data associated with the passenger who accessed the passenger keyboard and display apparatus installed on seat 30C, during a specific flight represented by the FLIGHT 1161 folder icon 1214, a specific date represented by SEPT. 15 folder icon 1216, and a specific month and year represented by the SEPT. 2004 folder icon 1218. The SEAT 30C folder icon 1204 contains the MY SEAT folder icon 1204, the ACTIVITY LOG document icon 1208, the PASSENGER document icon 1210, and the TARGETED ADS document icon 1212. It is understood that the SEAT 30C folder icon 1204 may contain other types of icons in addition to the aforementioned list. It is also understood that every passenger seat will be associated with a similar set of icons as the ones shown for seat 30C.

The MY SEAT folder icon 1206 contains data (such as Microsoft Word documents, multimedia files, and the like) saved by the user of the passenger keyboard and display apparatus installed on seat 30C.

The ACTIVITY LOG document icon 1208 represents data about the actions (such as visiting a website, viewing a movie, listening to music) performed by the user of the passenger keyboard and display apparatus. The PASSENGER document icon 1210 represents check-in information associated with the passenger. The TARGETED ADS document icon 1212 represents data about the advertisements that were shown to the user of the passenger keyboard and display apparatus.

FIGS. 157-158 show a flowchart for sending and delivering emails from an aircraft. FIG. 157 represents the sequence of actions that are perform by a user of the present invention in order to send emails using the passenger keyboard and display apparatus. FIG. 158 represents the sequence of actions that are performed by the system of the present invention in response to the sequence of user actions shown in FIG. 157.

In step 1220, the user of the passenger keyboard and display apparatus launches an email program (for example, Microsoft Outlook Express) that is accessible on the desktop user interface of the display apparatus. In step 1222, the user of the passenger keyboard and display apparatus composes an email by activating a Compose New Mail command available on the email program and entering the text of the email. Optionally, the user may also insert an attachment to the email during this step.

In step 1224, the user enters one or more recipient email addresses, and optionally a sender email address. If supplied, the sender email address is used by the system of the present invention to send a delivery confirmation notice to the user when the email is delivered. It is to be noted that the system of the present invention may automatically assign a virtual email address to a user of the passenger keyboard and display apparatus. The virtual email address is typically valid only for the duration of the flight, and is typically used to provide two-way email communication to the users of the present invention without requiring each user to have an actual email address. In step 1226, the user enters data for the other fields of the email, such as email addresses for the CC and BCC fields.

In step 1228, the user chooses an email delivery option. The user can choose between two options: Regular or Expedited. In the Regular email delivery option the email is temporarily stored in the aircraft email server's outbound queue, and is only relayed to a terrestrial mail server for delivery to the email's recipients when the aircraft lands. In the Expedited email delivery option the email is immediately relayed to a terrestrial mail server for delivery to the email's recipients. It is understood that the system of the present invention is not limited to the two email delivery options described herein, as other suitable methods may be used without departing from the characteristics of the present invention. The Regular email delivery option is typically offered as a free service to the aircraft's passengers, while the Expedited email delivery option is typically offered as a paid service, or as a free service available only to First Class passengers.

In step 1230, the user sends the email by activating a Send command available on the email program. This step initiates background processing tasks performed by the system of the present invention on behalf of the user. The sequence of actions representing the background processing tasks performed by the system is shown in FIG. 158. In step 1232 the system of the present invention displays a dialog box asking the user if he/she wants to send another email. If the user responds with Yes, he/she is redirected to step 1222. If the user responds with No, the user is directed to step 1234 in which the email program is automatically closed by the system and the user is returned to the desktop user interface.

FIG. 158 represents the sequence of actions that are performed by the system of the present invention in response to the sequence of actions performed by the user, as shown in the flowchart of FIG. 157. In step 1236, the system of the present invention determines the email delivery option chosen by the user in step 1228 of the flowchart shown in FIG. 157. If the user chose Regular, the system performs step 1238; if the user chose Expedited, the system performs step 1244.

In step 1238, the system stores the email in the aircraft mail server's outbound queue. It is understood that the email server on board the aircraft has sufficient data storage capacity to store emails. The step 1240 is performed only when the aircraft lands. In step 1240, the system of the present invention automatically relays the email to a suitable terrestrial mail server for eventual delivery to the email's intended recipients.

In step 1242, the system optionally sends a delivery confirmation notice to the sender of the email. Note that the system will perform this step if the user entered a sender email address in step 1224 of the flowchart shown in FIG. 157. In step 1244, the system connects to the aircraft's on board Internet gateway server for the purpose of establishing a connection to a terrestrial mail server. In step 1248, the system displays a delivery confirmation notice to the user, in the form of a pop up window or an icon in the desktop user interface of the present invention.

FIG. 159 shows a preferred method of promoting software and services to a captive audience such as the passengers aboard an aircraft. The sequence of actions described herein are performed by the system of the present invention and the operator of the system, i.e. the airline company. It is to be noted the the method described herein is not limited in applicability to passengers aboard an aircraft, but can be applied to passengers of other passenger vessels.

The step 1250 involves the installation of user terminals and supporting infrastructure necessary for the operation of the system. Supporting infrastructure includes but is not limited to server computers, local area network, connectivity to the Internet, fail over system, data backup system, operating systems, network security software, point of sales software, monitoring software, administrative software, and the like.

The step 1252 involves the installation of promotional software (also known as evaluation software) and services on the user terminals. Promotional software may also be installed to a shared location on a central server computer and accessed from that location by the users. The step 1254 involves the execution of targeting logic in order to select promotional software and services that closely match the user's interests, thereby increasing the chances of the user purchasing the software or subscribing to the service being promoted. It is to be noted that this step is optional, as targeting typically requires the availability of user profile data.

The step 1256 represents typical usage scenarios for promotional software and services. During this step the user typically forms impressions about the value of the software or services being promoted, affecting his/her decision to purchase the software or subscribe to the service. The step 1258 is an optional step that involves the installation of demos and tutorials to a location that can be accessed by the users of the system of the present invention.

In the step 1260, users are allowed to save or send data that may be produced by the promotional software or service. The data is typically saved in non-volatile memory, and may be archived for future reference. Typically, a printing service is also made available to users of the system to enable them to create hard copies of their data. The step 1262 involves making available facilities to enable users to purchase retail versions of promotional software or to subscribe to services. Typically, the aircraft operator employs facilities for secure payments, point-of-sales, shipping, and related facilities, to enable users to easily pay for items that they want to purchase.
